Description

Technical Field

[0001] This utility model relates to the field of spraying, specifically to a spraying device for magnesium-aluminum spinel spraying material for steel ladle lining. Background Technology

[0002] Magnesium-aluminum spinel blasting material for ladle lining is a refractory material specifically designed for use in steel production to protect the inner wall of the ladle (the container used to hold and transport molten steel) from corrosion. This blasting material is mainly made from raw materials such as magnesia and bauxite, and is formed through a specific process to create a material containing a magnesium-aluminum spinel structure.

[0003] A Chinese patent (application number: CN202222155513.2) discloses a spraying feeding device and a spraying machine. The spraying feeding device includes a storage tank, a heating unit, and a stirring unit. The storage tank has an upper storage chamber and a lower storage chamber, separated by a sieve plate. The upper storage chamber has an inlet, and the lower storage chamber has an outlet. The heating unit is connected to the storage tank and is used to heat the upper storage chamber. The stirring unit is also connected to the storage tank and is used to stir the paint in the lower storage chamber. The beneficial effects are: the heating unit heats the upper storage chamber, effectively reducing paint condensation; subsequently, liquid and smaller clumps of paint can be filtered through the sieve plate to reach the lower storage chamber; the paint in the lower storage chamber is stirred by the stirring unit to prevent further clumping. This spraying feeding device integrates heating, sieve filtration, and stirring, effectively reducing particle size.

[0004] Existing spraying equipment of this type has certain limitations in its structural design, such as inflexible spray position adjustment, fixed spray distance, and low degree of automation, resulting in uneven spraying, low efficiency, and even affecting the quality of the spraying. In addition, some devices lack effective sealing structures, which can easily cause dust leakage, affecting the working environment and the health of operators.

[0005] Therefore, this application provides a steel ladle lining magnesium-aluminum spinel spraying device with reasonable structure, convenient adjustment, good sealing performance and high-efficiency spraying, to solve the problems existing in the prior art. Summary of the Invention

[0027] like Figure 1-2 As shown, four grounding rods 101 are fixedly connected to the bottom of the support plate 1. The support vertical plate 2 is fixedly connected to the support plate 1. The transmission belt 3 is connected between the support vertical plates 2. An auxiliary block 201 is fixedly connected between the two ends of the two support vertical plates 2. The auxiliary block 201 is located at both ends of the transmission belt 3.

[0028] Specifically, the grounding rod 101 is used for support, and the support vertical plate 2 is used to assist in connecting the conveyor belt 3. In use, when an object is on the support vertical plate 2 and moves to the conveyor belt 3, it can be conveyed through the conveyor belt 3.

[0029] In this embodiment, transmission rods are provided at both ends of the inner wall of the conveyor belt 3, and a transmission motor 301 is provided on the outside of one of the supporting vertical plates 2. The output end of the transmission motor 301 is connected to one of the transmission rods.

[0030] In use, the rotation of the drive motor 301 can drive the transmission belt 3.

[0031] Example 3

[0032] like Figure 2-4 As shown, a contact block is fixedly connected to the bottom of the auxiliary head 5. The gear rack 6 and the limiting strip 7 are both fixedly connected to the auxiliary head 5. The contact block is connected to the supporting vertical plate 2 by screws. Gears are evenly arranged on the outside of the gear rack 6.

A positioning head 901 is provided on the outside of the extension plate 9. A rotating assembly 902 is provided between the extension plate 9 and the positioning head 901.

[0034] Specifically, the rotating component 902 is mainly used to assist in controlling the rotation of the positioning head 901 and to assist in positioning the transmission plate 8.

[0037] In this embodiment, the telescopic pipe 12 is a telescopic pipe structure, and the controller 13 is externally equipped with a control motor that can be connected to the spray head 14. The telescopic pipe 12 is connected to the storage box 11 and the spray head 14 respectively.
